SOUND REPRODUCTION DEVICE AND SOUND REPRODUCTION METHOD

摘要

Provided is a sound reproduction device that makes it possible to retain the feeling of width of a listening space even when a multichannel input audio signal is reproduced using speakers having different frequency characteristics. The sound reproduction device comprises: a sound source position parameter calculation unit (3) that calculates a sound image orientation position when reproduction is effected by both first and second speaker groups; a reproduction signal generation unit (4) that separates a sound signal representing a sound having a higher sound pressure level when reproduced by the first speaker group than when reproduced by the second speaker group, from a sound signal corresponding to the second speaker group, and generates a reproduction signal by adding the separated sound signal to a sound signal corresponding to the first speaker group; and a signal correction unit (8) and delay time adjustment unit (9) that correct the reproduction signal in such a way that a sound image that is oriented in accordance with the reproduction signal is oriented in substantially the same position as the calculated orientation position.
